Q: just downloaded music from itunes how do I add it to my ipod touch

Hey ericb2015,

You can easily do this in one of two ways. Make sure your iPod touch is plugged into your computer and then start by simply dragging songs towards your iPod touch and the song will sync over. The other way is going through the sync options within the Music tab of your iPod touch while it is plugged into your computer. Take a look at the articles below to give you more detailed instructions to get you listening to your music.
